Concrete splatter
I had asked the question a few day ago on how to remove concrete splatter from a cars surface. I found on the internet that Muratic Acid does the trick. Use it un- diluted. Sponge it on the concrete splatter and leave it on no more than 15 minutes. IT WILL NOT DO ANY DAMAGE TO THE PAINT. It eats up the concrete and make for a easy removal. Of course all wax is removed so a complete detailing is in order. Use gloves and a respirator, just for safety sake. The vehicle I did was my son's Lexas LS-430.

Warning
Before using any chemicals or solvents, carefully read all of the cautions and medical information on the products container and / or MSDS. Always follow all of the manufacturer’s recommendations. Ensure that you wear eye protection and acid-proof gloves; this is mandatory. No matter how safe an acidic product is advertised, never run the risk of it splashing in your eye or permeating your skin.
Ammonium hydrogen fluoride NH4HF2 or Ammonium bifluoride SiO2, is miss-classified as the safe alternative to hydrogen fluoride, once mixed with water it becomes hydrogen fluoride one of the most common, and dangerous, acid wheel cleaners used in automatic carwashes today. Its effectiveness removing brake dust and difficult contaminants from wheels is undisputed, but most chemists say Ammonium bifluoride presents an unjustifiable and potentially lethal risk. [Other names Hydrogen fluoride -Fluoric acid, Hydrofluoride, Hydrofluoric acid, Fluorine monohydride, Muric acid]
I would seriously reconsider before you us these acids, dilution of an acid doesn't make it safer as the addition of a molecule of water to a chemical compound, without forming any other products is known as hydration (i.e. dilution causes the pH to decrease)
A safe alternative- calcified water spots on paint and glass, water and concrete spots are pretty much the same chemically; calcium carbonate, with the concrete being cross-linked with water
Removal
•Apply 1:1 ratio water with distilled White Vinegar solution, and using a spray bottle, spray that mixture on the spots and let them "soak." Then rinse with water and repeat as necessary.
•If the ambient temperature water/vinegar mix does not work, warm (100-120 degrees) 100% distilled White Vinegar, saturate a clean kitchen sponge with pure vinegar and hold the sponge over the concrete spots for a few minutes
•If the above do not remove them try equal parts distilled water, isopropyl alcohol and distilled white vinegar. The acid in the vinegar will help etch and dissolve the concrete.
•Rinse the area thoroughly with water after the vinegar and then reapply wax or sealant to that area.
a) To remove concrete that has set use the A B C Decontamination / Neutralization system
(http:// www.autoint.com) a safe alkaline wash and neutralizing system the ABC wash apparently loosens the bond with the clear coat, after using the wash simply lift off any concrete with a plastic razor, for smaller specks use detailers clay, any subsequent etching will require an abrasive to level the paint surface, and then reapply wax or sealant to that area.
b) Back-Set by Romix is an acid alternative with no fumes or odours, molecularly breaks down the ionic bond in Portland cement, completely dissolving and releasing the hardened cement from any surface it is adhered to. Always apply Back-Set to a dry surface area- http://www. romixchem.com/
